The present invention relates to milk bottles and more particularly to a bottle having an attachment, by means of which either milk, or the cream which has risen from the milk, may be,

5 poured from the bottle according to the wishes of the user.

It is of course common knowledge that at the time milk is used by individuals, the cream has ordinarily risen and lies in a zone, usually in the neck of the bottle, over the milk which remains in the bottom or body portion. Many devices have been designed, by means of which the cream may be removed separately from the milk.

One object of the present invention is to provide a receptacle which is separate from the body portion of the bottle, and into which the cream will rise, and means for closing off the interior of the receptacle from the body portion of the bottle after the cream has risen.

. Another object is to provide means whereby the cream may be poured from the receptacle whenever it is so desired.

Still another object is to provide means whereby the milk may be poured from the milk chamher whenever it is desired without the necessity of first removing the cream.

These objects are accomplished in a practical manner by providing the milk bottle with a cream receptacle which fits into the. neck of the bottle,

and the bottom of which has an opening through which the cream may enter the chamber and a stopper for the opening which may be inserted after the cream has so risen. A vertical passage is formed between the receptacle and a wall of the bottle neck to connect the lower part of the bottle wherein the milk is contained and the mouth of the bottle. A special closure is provided for the mouth of the bottle, such closure having separately operable means whereby either the cream receptacle or the channel leading to the milk chamber may be opened, thus providing access to either.

Figure 12 is a perspective view of the modified form of cream receptacle.

Describing the drawings more particularly the bottle l3 may be constructed having a lower or milk-containing portion l4, as is usual with milk bottles, and an upstanding neck l5. The upstanding neck I5, as shown in Figures 1-7 inelusive, may advantageously be formed in subv stantially the shape of a diamond having two points or apices l6 and H, respectively. Preferably the bottle walls are outwardly flared near the mouth of the bottle at these apices to form pouring lips It. For separating the cream from the milk, a cream receptacle is removably positioned in the neck of the bottle. This cream receptacle has side walls I9 arranged in such fashion that when the receptacle is placed in the neck of the bottle the receptacle makes close contact with the inner sides of the neck of the bottle, with the exception that one apex of the receptacle is truncated, so that a passage 26 is left at this point between the receptacle and the interior of the bottle neck and aiiording a means of exit to the milk in the body portion of the bottle. This receptacle may be made of any suitable material.

The bottom wall 2i of the receptacle has an opening 22 through which the cream may rise into the receptacle. An outwardly extending lip or flange 23 at the top of the receptacle engages a shoulder 24 formed at the mouth of the milk bottle. Preferably this flange extends completely around the mouth of the milk bottle, having an extension in the form of a loop 25 extending beyond the wall 20 for the purpose of forming a continuous seat about the mouth of the bottle for the reception of a closure. The flange 23 serves to position the cream receptacle with respect to the neck of the bottle and serves also as a seat for a gasket 26 which may overlie it. The receptacle may be provided with a lip 21 corresponding to and engaging the interior of one of the lips it of the bottle. Preferablythe bottom wall 2i is outwardly concaved in order to guide the cream to the port 22.

In order to separate the interior of the receptacle Hi from the bottom portion I4 of the bottle, the following structure is provided. A plug 28 for the opening 22 is mounted on a rod 29 which extends upwardly to a point above the top of the bottle when the plug is positioned in the opening 22. Preferably the top of the rod is threaded as at 30 in order to receive a boss 3| which is secured to a closure 32 of suitable size and. shape, to close the mouth of the bottle.

A nut 33 suitably shaped to form a handle may be mounted on the end of the rod. The cover 32 is positioned longitudinally of the rod at the proper point, so that when the plug 26 is posi- 5 tioned in the opening 22, the cover will closely engage the flange 23 of the receptacle id in a gasket, as 26, and effectively stop the bottle.

The gasket 28 may or may not be necessary,..

depending on the configuration of the bottle mouth and the material of the cap. In order to give access to either the cream receptacle or the channel 20, the portions of the closure corresponding to the apices of the diamond shaped neck of the bottle are in the form of flaps 34 and 35 respectively which are hinged to the cover and may be provided with lifting tabs 36.

It is thought that the manner of use of the device will be obvious. The cream receptacle i8 may be inserted in the bottle with the opening or port 22 open. When the cream has risen the rod 29 may be attached to the cover 32 and the plug inserted in the opening 22 with the closure 32 closing the mouth of the bottle and the plug stopping communication between the interior of the receptacle l8 and the body portion 14 of the bottle. Either cream or milk may now be poured into the bottle by opening the proper flap M or 35 and tilting the bottle in the proper direction.

In the modified form shown in Figures 9 to 12 inclusive, the milk bottle has a bottom or body portion it and an upstanding neck ti, which is substantially round in cross section, as

shown in Figure 11, with the exception that it has a substantially V-shaped extension forming a channel 32 extending to one side thereof.

The body of the cream receiving receptacle 43, as shown in Figure 12, is in substantially the form of a cylinder and has a projection 44 on one side that extends into and closes off the channel 42, and the wall 35 of which separates the interior of the channel from the interior of the cream receptacle. The bottom wall 45 of the 45 receptacle has an opening 47 therein similar to the opening 22 of the preferred embodiment, and this is adapted to be closed by a plug" l8 mounted on a rod 49 which passes through a cap 50.

5 The cap 58 is of proper shape and size to effectually close the bottle mouth and it is provided with a flap portion 5| which is hinged to the cover 5t, and which gives access to the interior of the cream receptacle. A similarly hinged flap portion 52 overlies the opening of the channel and acts as a closure therefor. The mode of using this modified form is exactly similar to that of the preferred embodiment.

From the foregoing it is thought that the con- 60 struction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim is:
